Chemical Structure

(1S,4AS,5S,7R,7aR)-1-methoxy-7-methyloctahydrocyclopenta[c]pyran-5,7-diol CAS 55732-36-0 chemical structure

Description

(1S,4AS,5S,7R,7aR)-1-methoxy-7-methyloctahydrocyclopenta[c]pyran-5,7-diol (C10H18O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

(1S,4AS,5S,7R,7aR)-1-methoxy-7-methyloctahydrocyclopenta[c]pyran-5,7-diol (CAS 55732-36-0) is a high-purity analytical reference standard with the molecular formula C10H18O4 and a molecular weight of 202.25 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
